What's the current status?

Our current implementation is working less well since we upgraded
Linux to 4.x, and apparently even worse on our Debian Stretch -based
ISOs: memory wipe works fine, but something weird happens in the
initramfs that breaks shutdown. So a more robust replacement would be
warmly welcome :)

However, we're looking into shipping a kernel with the grsecurity
patch, and sadly, the GRKERNSEC_KMEM feature removes support for
kexec. That feature is enabled in the Debian grsec kernels, and can't
be disabled at runtime if compiled in. Any thoughts about this?

Cheers,
